Exhibit 99.1

ENDPOINTS MET IN FIRST STAGE OF ADVENTRX COFACTOR

PHASE II METASTATIC COLORECTAL CANCER STUDY

Patient Enrollment Completed in Phase II Study

SAN DIEGO - January 25, 2005 - ADVENTRX Pharmaceuticals, Inc. (Amex: ANX) today announced that the primary endpoint for response rate and the secondary endpoint for safety were met in the first stage of its Simon two-stage design Phase II trial using CoFactor™ to modulate the effect of 5-fluorouracil (5-FU) in patients with metastatic colorectal cancer. The Company further announced that patient enrollment is complete in this Phase II study. The Company currently expects to announce a complete summary of study results in the second quarter of this year.

The Phase II study, entitled “COFU: a multi-center Phase II clinical trial to evaluate the safety and efficacy of weekly treatment with CoFactor’ and 5-fluorouracil in patients with metastatic colorectal carcinoma,” is an open-label, single-arm study to evaluate safety, tumor response, time-to-tumor progression and overall survival in metastatic colorectal cancer patients treated with CoFactor and 5-FU. A total of 50 patients were recruited for this trial.

“We are pleased with our clinical progress and we currently plan to report summary clinical results from the entire Phase II trial this spring,” said Cellia Habita, M.D., Ph.D., ADVENTRX senior vice president of clinical and medical affairs. “We initiated this trial on the strength of earlier Phase I/II results that demonstrated CoFactor administered with 5-FU appeared to show improvement of objective response and time-to-tumor progression and reduced toxic side effects in colorectal, pancreatic, gastric and breast cancers.”

“We are encouraged that the first stage of the Phase II clinical trial met both the primary and secondary endpoints,” said Evan M. Levine, ADVENTRX president and chief executive officer. “Meeting our stage I endpoints and completing patient enrollment mark additional important milestones in our efforts to move CoFactor through the clinical process. We are currently in the process of applying for additional clinical studies with CoFactor administered in combination with other regimens in metastatic colorectal, advanced pancreatic, and late stage gastric cancers with the goal of filing an NDA in late 2007.”

ADVENTRX presently intends to file for clearance in the first quarter of 2005 in both the US and European Union to begin randomized controlled multi-center metastatic colorectal cancer trials with CoFactor and 5-FU as a first-line therapy. The Company also currently intends to file in the EU in the second quarter of 2005 to begin a clinical trial in patients with advanced pancreatic cancer. In October 2004, the Company was granted orphan drug status for CoFactor for the treatment of pancreatic cancer in the US and EU.
